摘要
国内外资料表明 ,地应力对煤层渗透性有显著影响 ,通过实验室和试井资料分析发现 ,煤层渗透率与地应力呈幂指数相关关系 ,据此可以在某种程度上预测煤层的渗透性。
The information from China and abroad indicates that in situ stress has remarkable effect on coalbed permeability.From the analyses of the data of laboratory and test,it is found that coal reservoir's permeability of China have an index relationship to in situ stress.To some extent,this relationship can be used to forecast the permeability of coalbed.
